Hercules® Megaloc® is a multi-purpose thread sealant made with DuPont™ Kevlar® for use on metals, including steel, stainless steel, brass, copper, aluminum and plastics. Megaloc® wipes clean from hands and tools with a dry rag, is odor-free, grit-free and will not separate or settle. Megaloc® does not harden, crack or become brittle rather the joints can be disassembled without damage to pipe, fittings or threads years after the joint was made. Megaloc® is applied easily with a natural bristle brush even at temperatures as low as -25 deg F and performs over a temperature range of -50 to 400 deg F. It provides leakproof hydraulic resistance to 12,000 psi and withstands gas pressure up to 2600 psi. Megaloc® is non-toxic, non-hazardous and non-flammable and contains no lead, heavy metals or volatile solvents.
